PHP4 with Informix driver make error

Hi, Here is my problem : I wanted to use PHP with Informix (IDS2000-9.21.UC3-1). Well the two components are installed, but the Informix driver is not supplied with PHP (I saw that by running a call to phpinfo() in a php page in my browser. So I look the configure line -of the RPM installation- provided by phpinfo() -too- and I see that, in fact, there is no "--with-informix" or "--with-informix=yes". So I download sources, I want to use the same line, wut now with "--with-informix" at the end. Here is the new line : --------- ./configure --prefix=/usr --with-config-file-path=/etc --disable-debug --enable-pic --enable-shared --enable-inline-optimization --with-apxs=/usr/sbin/apxs --with-exec-dir=/usr/bin --with-regex=system --with-gettext --with-gd=shared --with-jpeg-dir=/usr --with-png --with-zlib --with-db2 --with-db3 --with-gdbm --enable-debugger --enable-magic-quotes --enable-safe-mode --enable-sysvsem --enable-sysvshm --enable-track-vars --enable-yp --enable-ftp --without-mysql --without-oracle --without-oci8 --with-openssl --with-xml --with-informix ---------- this line works well. So I run "make" to compile sources, and then I have this error : ---------- stub.lo: file not recognized: File truncated ---------- I read in this mailing-list that deleting the file "stub.lo" resolved the problem, but when I did that, I had another error : ---------- main/.libs/libmain.al: object main/.libs/libmain.al(main.lo) in archive is not object ---------- I don't want to delete all files to do php+informix work ! So if someone could help, it would be very appreciated ;-) thx, Bastien.
